Subscription

Hi Everyone

I have a question...

I have the individual subscription for apple music and I just used it on my iPhone today I was trying to play music in my computer but there is anything about the subscription so I follow some steps go to account and try to sign in but when I used my information showed as incorrect but is the same user and password that I use so that means I have to get another subscription if I want to play music from my Mac because no make any sense for me
